Answers

Answer:

[tex]\frac{1}{10}[/tex]

Step-by-step explanation:

1/4 of 2/5 = 1/4 * 2/5

Step-by-step explanation:

In the figure below, DOG, ION, and IDO are congruent and isosceles, each with perimeter 55. The quadrilaterals FLIN, DIES, and DRAG are all squares. The perimeter of the 11-sided polygon DRAGONFLIES is 127.

What is the area of DRAG?

Answers

Let's call the sides that are length  DG " s " .

And let's call the sides that are length  GO  " t ".

Since the perimeter of each triangle is 55...

s + t + t  =  55

s + 2t  =  55

2t  =  55 - s

Since the perimeter of the entire figure is 127...

9s + 2t  =  127            

Since  2t = 55 - s  ,  we can replace  2t  with  55 - s .

9s + (55 - s)  =  127

8s + 55  =  127             Subtract  55  from both sides.

8s  =  72                       Divide both sides by  8  .

s  =  9

And...the area of the square DRAG  =  DG2  =  s2  =  92  =  81 sq. units.

Which equation represents the cost of a phone call, c, in cents, after m minutes, according to the payment plan?
A. c=1/6m
B. c=6m
C. c=1/30m
D. c=30m

Answers

Answer:

B

Step-by-step explanation:

Slope equals rise over run so the slope of this line is 30/5 or 6. That means for every minute calling you would have to pay 6 cents which is shown in the equation c=6m.

B!

the slope of the line represents the rate of the plan and can be calculated by using the change in y values divided by the change in x values of two points on the line. In this case, it would be easiest to pick 0 and 6 as y values, and 0 and 1 as x values. then,

slope = (6-0) / (1-0)
slope = 6/1
slope = 6

therefore the slope is 6 and the correct equation is B: c=6m

HELP , BRAINLIEST IF CORRECT, rewrite each equation without absolute value for the given conditions: y=|x-3|+|x+2|-|x-5| if 3

Removing the absolute value signs you would have y= x-3 +x +2 -x - 5 if 3. I don’t understand what you are asking for tho so if you were to solve for the absolute value it would be: y= x + 3 + x + 2 - c + 5 if 3.

PLEASE HELP QUICK
Is this triangle acute, right, or obtuse?

acute

right

obtuse

Answers

Answer: Obtuse

This is because the lower left angle is larger than 90 degrees. This is assuming the triangle is drawn to scale (i.e. drawn accurately).

Any time there's an angle larger than 90, the triangle will be obtuse. If there's one angle exactly 90, then it's a right triangle. Otherwise, the triangle is acute (when all angles are smaller than 90).

This is obtuse!
How I know?
Well, the triangle is more than 90 degrees, making it obtuse. If it was 90 degrees, it’d be considered a right angle. And if it’s less than 90 degrees, it’s acute.

y=2x+6

Step-by-step explanation:

slope intercept formula → y=mx+b

[tex]\frac{6-2}{0-(-2)} =\frac{4}{2} =2\\[/tex]

so 2 is your slope and the point (0,6) crosses the y-intercept at 6 since x = 0

plugin 2 for m (or the slope) and 6 for b (y-intercept)

The Smith family has a circular shaped pool with a radius of 10 feet. What is the minimum amount of material needed to make a cover for the surface of the pool?

62.8 sq. feet

314 sq. feet

31.4 sq. feet

100 sq. feet

Answers

Answer:

314 sq. feet

Step-by-step explanation:
The surface area of the pool would be the area in math. The equation for solving the area of a circle goes as follows:

A=πr^2
π·10^2
314

Answer:

A

Step-by-step explanation:

A circular shaped pool.

The radius is 10 feet.

We need to find the surface area to make a cover for the pool.

We can use the formula for the area of a circle:

A = [tex]\pi[/tex]r²

A = (3.14)(10)(2)

A = (31.4)(2)

A = 62.8

The minimum amount of material needed to make a cover is 62.8 square feet.

Answer:

y = 17/3x - 26

Step-by-step explanation:

Remember the slope formula:

[tex]m = \frac{y2-y1}{x2-x1} \\[/tex]

[tex]m = \frac{-9-8}{3-6}\\\\m = \frac{-17}{3}\\\\m = \frac{17}{3}[/tex]

Slope: 17 / 3

First part of equation: y = 17/3x + b

To find b, plug in the values from the points we know:

[tex]-9 = \frac{17}{3} * 3 + b\\-9=17+b\\b+17=-9\\b=-26\\[/tex]

Therefore, the Y-intercept is -26

Combining all the parts, the answer is y = 17/3x - 26
